I will be running in a 100km ultramarathon held on the Shimanto River in Kochi Prefecture, which is said to be the last source of the river!

I will challenge myself to see if I can put the experience I have gained from trail running to good use! ● Running log data (Strava) / strava ● Items worn (excerpt) ・Cap https://www.patagonia.jp/home/ ・T-shirt https://a.r10.to/h5lvKP ・Shorts https://a.r10.to/hPt9MI ・Socks https://amzn.to/3Qmp8kP ・Waist bag https://a.r10.to/hkQfOq ・Shoes https://a.r10.to/hgGKri ・Watch https://amzn.to/46RUEg8 ・Heart rate monitor https://amzn.to/3tJUoRT ・Gachio Project G items https://www.gachio-ch.com/project-gi... ● Food and gels prepared https://amzn.to/46XkijM ・ANDO_ https://a.r10.to/hueIP0 ・Katsusup https://www.staminasports.jp/・Salt gel https://a.r10.to/hNWh0C *Links include affiliate links ■Subscribe to the channel here: http://bit.ly/2LiaF6Q ■Instagram: / gachio_ch ■Threads: https://www.threads.net/@gachio_ch ■X (Twitter): / gachio_running ■note: https://note.com/gachio_running ■Strava: https://strava.app.link/Gachio ■Gachio website https://www.gachio-ch.com/ ■Gachio Radio now on air!
